This study analyzed how urban vegetation influences the formation and (Normalized Difference Vegetation Index NDVI and Green Area Index GAI), urbanization indices (Normalized Difference Built-Up Index NDBI and Built-Up Index BU), and thermal indices (Land Surface Temperature LST, Thermal Discomfort Index TDI, and Urban Thermal Field Variation Index UTFVI) were used. Data were obtained from the OLI sensor aboard Landsat 8, in addition to demographic data from the Brazilian Institute of Geography and Statistics (IBGE) and meteorological data from the National Institute of Meteorology (INMET) for the years 2013 and 2023. The results indicate that areas with greater vegetation cover showed milder surface temperatures, while densely urbanized neighborhoods, such as the city center and the industrial district, recorded the highest UHI levels. The UTFVI index revealed an intensification of urban thermal stress over the decade, correlated with increased urbanization and the reduction of green areas. The correlation among indices demonstrated that vegetation plays a moderate role in mitigating thermal stress in Vitória; however, its uneven distribution creates microclimates that impact neighborhoods heterogeneously. This study highlights the need for urban policies that prioritize the expansion and preservation of green areas to mitigate UHI effects and promote greater thermal comfort for the population

However, the use of CCA raises environmental concerns due to the potential leaching of heavy metals such as chromium (Cr), copper (Cu), and arsenic (As), which can pose risks to the environment and public health. This study aimed to isolate and identify lignocellulolytic fungi with the potential for CCA detoxification in treated eucalyptus wood in use in the southern region of Espírito Santo. Samples of CCA-treated Eucalyptus spp. wood were collected from areas at different altitudes in the municipality of Jerônimo Monteiro - ES, showing signs of fungal degradation. After the isolation process and phenotypic identification, 21 fungal morphotypes were initially characterized, of which 19 were visually classified as distinct after refinement. Cultures were tested for resistance to Cr, Cu, and As concentrations, separately in supplemented culture media, in which eight isolates showed uninterrupted growth at all evaluated concentrations (2, 4, 6, and 8 g L¹) calculated in oxide base. The fungi with notable resistance were subjected to genetic analysis and identified as belonging to the genera Penicillium and Paecilomyces. Specifically, Penicillium wotroi, Penicillium citreosulfuratum, and Paecilomyces lecythidis were identified. Literature suggests that these genera have biotechnological potential due to their ability to metabolize heavy metals through organic acids and ligninolytic enzymes. Special attention was given to the fungi Penicillium citreosulfuratum and Paecilomyces lecythidis. One fungus, Penicillium citreosulfuratum, and a variant of Paecilomyces lecythidis also demonstrated growth capability in commercial CCA-supplemented media (6.5 g L m-3). The results indicated that greater resistance and adaptability to heavy metals were observed in fungi originating from mid-altitudes (150 550 m) and high altitudes (600 800 m), suggesting that natural environmental selection facilitates the evolution of these species in CCA-exposed environments. This study confirms the hypothesis that fungi with bioremediation potential exist in the studied region, highlighting pathways for the application of these species in bioremediation strategies for treated wood residues. Finally, the importance of further investigations for genetic confirmation and exploration of the biotechnological potential of these species is emphasized

In areas with low and irregular rainfall, water scarcity may lead to stomatal closure, adversely affecting transpiration, gas exchange, photosynthesis, and consequently, plant development. The use of innovative technologies, such as thermographic imaging, has proven to be a promising tool for monitoring plant water stress. This study aimed to evaluate the potential use of thermographic images of eucalyptus leaves in determining stomatal conductance, leaf water potential, and soil water content under different atmospheric demand and soil water availability conditions.The experiment was conducted in an open area at the Laboratory of Meteorology and Forest Ecophysiology, Federal University of Espírito Santo, located in Jerônimo Monteiro, Espírito Santo, Brazil. Three field campaigns were carried out in April, May, and August 2024, with the aim of collecting data under varying atmospheric conditions, particularly solar radiation, temperature, and atmospheric vapor pressure deficit. Seedlings of the hybrid Eucalyptus urophylla × Eucalyptus grandis clone I144 were planted in 12-liter pots and grown for approximately 30 days, with irrigation initially maintained near 90% of the maximum soil water retention capacity (MWRC). During each campaign, once the plants reached approximately 0.5 m² of leaf area, irrigation was suspended for a subset of plants, and the following water supply levels were implemented: full irrigation, moderate water restriction, and severe water restriction. These levels were defined by maintaining the substrate at 90%, 60%, and 30% of the MWRC, respectively. Five replicates were adopted, totaling 15 plants per campaign. On the final day of each campaign, water consumption, gas exchange, stomatal conductance, leaf water potential, and leaf temperature were measured to characterize plant physiological responses. Additionally, throughout the campaigns, daily measurements were taken at 10 a.m. for soil water content, stomatal conductance, and leaf temperature, while predawn leaf water potential was measured to model the physiological variables and soil water content as a function of leaf temperature and the temperature difference between air and leaf . Data were subjected to analysis of variance, and when significant differences were found using the F-test at the 5% level, means were compared using Tukey's test at the same significance level. For modeling purposes, second-order polynomial models were fitted to describe the relationships among variables, and two regression algorithms were employed: Random Forest Regressor (RFR) and K-Nearest Neighbors Regressor (KNN). Model accuracy was assessed using the coefficient of determination (R²), standard error of estimate (SEE), and root mean square error (RMSE). The results demonstrated a significant impact of water restriction on the ecophysiology of eucalyptus by the end of the campaigns, with stomatal closure emerging as the primary control mechanism. Furthermore, thermographic imaging proved useful in determining leaf water potential, soil moisture content, and particularly stomatal conductance, highlighting its applicability in assessing plant water status
- ItemEfeitos da adição de lã de vidro à resina ureia-formaldeído nas propriedades de painel aglomerado homogêneo(Universidade Federal do Espírito Santo, 2025-04-15) Fassarella, Michelângelo Vargas; Chaves, Izabella Luzia Silva; https://orcid.org/0000-0002-3808-0136; http://lattes.cnpq.br/1057676508843699; Gonçalves, Fabrício Gomes; https://orcid.org/0000-0003-2010-9508; http://lattes.cnpq.br/0616694853822879; https://orcid.org/0000-0003-4495-6058; http://lattes.cnpq.br/4157179239531243; Lelis, Roberto Carlos Costa; https://orcid.org/0000-0003-2923-3839; http://lattes.cnpq.br/5175502780570226; Paes, Juarez Benigno ; https://orcid.org/0000-0003-4776-4246; http://lattes.cnpq.br/3454401627877927The improper disposal of glass wool waste poses an environmental challenge, where its utilization in materials engineering represents a sustainable strategy to mitigate impacts and enhance the performance of composites. This research examined the incorporation of glass wool (GW) waste as a filling material in urea formaldehyde (UF), assessing its effects on the properties of the adhesive and its influence on the physical-mechanical, fireproof, and acoustic properties of engineered wood panels. Panels with a target density of 700 kg.m-3 were produced using different proportions of glass wool in the adhesive (T1: 0%; T2: 3.34%; T3: 4.93%; T4: 6.52%; T5: 9.49%; T6: 12.35%). Manufactured in a hydraulic press at 160 ºC with a compression force of 72 tons and a pressing duration of 10 minutes, a ratio of 12% adhesive was maintained concerning the dry mass of the wood particles. Auxiliary analyses, such as the characterization of the filling material, included X-ray diffraction, thermogravimetry, and infrared spectroscopy, while the panels underwent densitometric profile analysis and scanning electron microscopy. The statistical analysis involved regression, variance analysis, and the Scott-Knott test (p < 0.05). Hierarchical clustering, principal component analysis, and Pearson correlations allowed for the identification of factors and verification of the strength of associations among the parameters. The results indicated that the addition of 3.39% of GW to the adhesive improved dimensional stability, the modulus of rupture, internal bonding, and screw withdrawal of the panels. In contrast, higher contents increased the damping factor and fire resistance. These findings highlight the potential of glass wool as a functional additive, promoting the development of safer and more sustainable composites
- ItemPotencial da regeneração natural como estratégia para restauração ecológica da Mata Atlântica no Espírito Santo(Universidade Federal do Espírito Santo, 2025-04-14) Angelo, Mônica Pagio de; Dan, Maurício Lima; https://orcid.org/0000-0002-1483-081X; http://lattes.cnpq.br/4634459670843421; Kunz, Sustanis Horn; https://orcid.org/0000-0001-6937-7787; http://lattes.cnpq.br/0203797981088640; https://orcid.org/0009-0006-8815-3176; http://lattes.cnpq.br/6731030166565223; Dias, Patricia Borges; https://orcid.org/0000-0002-5227-8341; http://lattes.cnpq.br/1194831380343570; Sapdeto, Cristiani; https://orcid.org/0000-0002-9285-6636; http://lattes.cnpq.br/Successive land-use cycles in tropical regions, driven by agricultural and logging activities, have led to the fragmentation and loss of native forest cover, threatening biodiversity and ecosystem services. In this context, natural regeneration emerges as a potentially viable strategy for ecological restoration, particularly in areas with forest remnants and seed dispersing fauna. This study aimed to investigate the potential of natural regeneration in areas with different abandonment ages in southern Espírito Santo, Brazil, to inform ecological restoration efforts. Four areas representing different successional stages were assessed: mature forest (MM), tall secondary forest (CA), low secondary forest (CB), and degraded pasture (PS). In each area, five plots measuring 4 m × 8 m (160 m² per area) were established, and all individuals with a minimum height of 60 cm and a diameter of at least 2.0 cm at ground level were inventoried. Structural parameters (density and dominance), diversity metrics (Shannon index [H’] and Pielou’s evenness), and floristic similarity (Jaccard index, Venn diagram, non-metric, multidimensional scaling [NMDS], and Morisita-Horn overlap index) were calculated. A total of 526 individuals were recorded, distributed across 33 families, 72 genera, and 118 species, with Sapotaceae, Fabaceae, and Myrtaceae being the most represented families. The abundance of individuals did not differ significantly (p < 0.05) among MM (155), CA (153), and CB (132), but PS showed significantly lower values (86). The diversity of CA (H’ = 3.43) was comparable to MM (H’ = 3.14), both higher than those observed in CB (H’ = 1.51) and PS (H’ = 0.75). The most abundant species were Dalbergia nigra (Vell.) Allemão ex Benth., Actinostemon klotzschii (Didr.) Pax, and Varronia curassavica Jacq. According to the IUCN, D. nigra is classified as vulnerable and Couratari asterotricha Prance as endangered. MM and CA showed a predominance of zoochoric species, indicating progression toward later successional stages through natural regeneration. In contrast, CB and PS were dominated by pioneer species and exhibited low diversity. Floristic similarity between areas was low a common pattern in tropical forests likely influenced by historical land use, which plays a significant role in shaping forest regeneration dynamics. MM stood out for its advanced successional stage, moderate diversity, and presence of indicator species associated with mature ecosystems, such as those from Lauraceae, Myrtaceae, and Sapotaceae, serving as a reference point for restoration actions. Although still recovering, CA shared several features with MM, such as high Shannon diversity and a dominance of zoochoric dispersal, suggesting consistent successional advancement. Meanwhile, CB and PS, representing early successional stages, were characterized by a prevalence of pioneer species and low functional diversity. The high floristic dissimilarity among areas highlights the influence of multiple ecological and environmental factors, underscoring the importance of site-specific management approaches. Strategies such as enrichment planting with zoochoric species and the control of invasive grasses may accelerate ecological succession, enhancing connectivity and structural complexity. In conclusion, natural regeneration holds potential for ecological restoration, particularly in less degraded areas like CA, whereas CB and PS require adaptive management to overcome limitations in diversity and functional recovery
